Description of Related Art

With the development of wireless communication technologies, an electronic device (e.g., an electronic device for communication) is commonly used in daily life, and thus the level of user demand has increased. Various types of wireless communication technologies are used to meet the level of user demand. For example, wireless communication technology may include at least one of ultra-wideband (UWB) communication, wireless fidelity (Wi-Fi) communication, long term evolution (LTE) communication, 5G communication (or new radio (NR) communication), or Bluetooth communication.

A frequency resource used for wireless communication by an electronic device may be limited. Accordingly, in at least a part of a plurality of wireless communication schemes available by an electronic device, at least a part of frequency bands may overlap. For example, a UWB communication scheme may support a frequency band of 6.25 GHz to 8.25 GHz. A wireless fidelity (Wi-Fi) communication scheme may support a frequency band of 2.4 GHz to 2.5 GHz and a frequency band of 5.15 GHz to 7.15 GHz. For example, in the UWB communication scheme and the Wi-Fi communication scheme, a frequency band of 6.25 GHz to 7.15 GHz may overlap.

When an electronic device simultaneously uses wireless communication schemes in which frequency bands overlap, communication quality may deteriorate or communication failure may occur due to communication interference between the schemes.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

Referring to FIG. 2A, an electronic device 201 may include a processor (e.g., including processing circuitry) 210, a first communication circuit 220, a second communication circuit 230, a plurality of switches 240 and 242, a diplexer 250, a filter 260, and/or a plurality of antennas 270 and 271.

According to an embodiment, the processor 210 may be substantially the same as or similar to the processor 120 of FIG. 1 or may be included in the processor 120. According to an embodiment, the first communication circuit 220 and the second communication circuit 230 may be substantially the same as or similar to a wireless communication module 192 or may be included in the wireless communication module 192. According to an embodiment, the plurality of antennas 270 and 271 may be substantially the same as or similar to an antenna module 197 or may be included in the antenna module 197.

According to various embodiments, the processor 210 may include various processing circuitry and control at least one other component (e.g., a hardware or software component) of the electronic device 201. According to an embodiment, when the occurrence of an event (e.g., an active event) related to the second communication circuit 230 is detected, the processor 210 may transmit information related to the event to the second communication circuit 230. For example, the information related to the event may include at least one of information (e.g., a service type) related to a service provided through the second communication circuit 230 or an active signal of the second communication circuit 230. For example, the processor 210 may determine whether an event (e.g., an active event) related to the second communication circuit 230 occurs, through Bluetooth or Bluetooth low energy (BLE). For example, the processor 210 may be connected to the first communication circuit 220 through a peripheral component interconnect express (PCIe) interface. For example, the processor 210 may be connected to the second communication circuit 230 through a serial peripheral interface (SPI).

According to various embodiments, the first communication circuit 220 may, for example, and without limitation, support a first frequency band (e.g., 2.4 to 2.5 GHz, or 5.15 to 7.25 GHz) or at least a part (e.g., 2.4 to 2.5 GHz, or 5.15 to 7.15 GHz) of the first frequency band, based on a first communication scheme (e.g., a Wi-Fi communication scheme). According to an embodiment, the first communication circuit 220 may transmit and/or receive data to and/or from an external electronic device (e.g., the electronic device 102 of FIG. 1 ) through a first antenna 270 configured to support the first frequency band. For example, the first antenna 270 may support a frequency band of 2.4 to 7.25 GHz including the first frequency band.

According to various embodiments, the first communication circuit 220 may determine a communication circuit for using the first antenna 270. According to an embodiment, when the first communication circuit 220 has received information related to a service priority of the second communication circuit 230 from the second communication circuit 230, the first communication circuit 220 may select the first communication circuit 220 or the second communication circuit 230 as a communication circuit for using the first antenna 270, based on the service priority of the second communication circuit 230. For example, when the first communication circuit 220 does not provide a first communication service (e.g., a Wi-Fi communication service), the first communication circuit 220 may determine that the second communication circuit 230 uses the first antenna 270. For example, the first communication circuit 220 may determine that a communication circuit having a relatively high service priority among the first communication circuit 220 and/or the second communication circuit 230 uses the first antenna 270. For example, when service priorities of the first communication circuit 220 and the second communication circuit 230 are the same, the first communication circuit 220 may determine that the first communication circuit 220 and the second communication circuit 230 alternately use the first antenna 270. For example, the first communication circuit 220 may be connected to the second communication circuit 230 through a universal asynchronous receiver/transmitter (UART) interface. However, the disclosure is not limited thereto.

According to various embodiments, the second communication circuit 230 may, for example, and without limitation, support at least a part (e.g., 6.25 to 7.25 GHz) of the first frequency band and a second frequency band (e.g., 7.25 to 8.25 GHz), based on a second communication scheme (e.g., a UWB communication scheme). According to an embodiment, when the second communication circuit 230 uses channel 8 or channel 9, the second communication circuit 230 may transmit and/or receive data to and/or from an external electronic device through a second antenna 271 configured to support the second frequency band. According to an embodiment, when the second communication circuit 230 uses channel 5 or channel 6, the second communication circuit 230 may transmit and/or receive data to and/or from an external electronic device through the first antenna 270 configured to support the first frequency band (e.g., 2.4 to 7.25 GHz). For example, the second antenna 271 may support a frequency band of 7.25 to 8.5 GHz including the second frequency band.

In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, an order of each operation may be changed, and at least two operations may be performed in parallel. For example, an electronic device may be the electronic device 101 of FIG. 1 or the electronic device 201 of FIGS. 2A, 2B, 2C, 2D, 2E and 2F (which may be referred to hereinafter as FIGS. 2A to 2F for convenience).

Referring to FIG. 3 , according to various embodiments, in operation 301, a second communication circuit (e.g., the wireless communication module 192 of FIG. 1 or the second communication circuit 230 of FIGS. 2A to 2F) of the electronic device may determine whether to provide a second communication service (e.g., a UWB service) using a first frequency band. According to an embodiment, the second communication circuit 230 may identify a frequency band to be used to provide the second communication service (e.g., the UWB service), based on information related to an event received from a processor 210. For example, the information related to the event may include at least one of information (e.g., a used frequency band and a service type) related to a service provided through the second communication circuit 230 or an active signal of the second communication circuit 230. For example, the second communication circuit 230 may maintain an inactive state until the information related to the event is received from the processor 210. For example, the first frequency band may include 2.4 to 2.5 GHz, or 5.15 to 7.25 GHz, a first communication circuit 220 may support at least a part (e.g., 2.4 to 2.5 GHz, or 5.15 to 7.15 GHz) of the first frequency band, and the second communication circuit 230 may support at least another part (e.g., 6.25 to 7.25 GHz) of the first frequency band.

According to various embodiments, when the first frequency band is not being used for the second communication service (e.g., the UWB service) (e.g., “No” in operation 301), the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may determine that a second frequency band (e.g., 7.25 to 8.25 GHz) is being used for the second communication service (e.g., the UWB service). According to an embodiment, when the second communication circuit 230 uses the second frequency band (e.g., 7.25 to 8.25 GHz) for the second communication service (e.g., the UWB service), the second communication circuit 230 may transmit and/or receive, to and/or from an external electronic device (e.g., the electronic device 102 of FIG. 1 ), data related to the second communication service (e.g., the UWB service) through the second antenna 271 of FIG. 2A, which is configured to support the second frequency band.

According to various embodiments, when the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device provides the second communication service (e.g., the UWB service) using the first frequency band (e.g., “Yes” in operation 301), in operation 303, the second communication circuit may transmit information related to a service priority of the second communication circuit (e.g., the second communication circuit 230) to the first communication circuit (e.g., the wireless communication module 192 or the first communication circuit 220) of the electronic device. According to an embodiment, the second communication circuit 230 may transmit information related to a priority of a service provided by the second communication circuit 230 to the first communication circuit 220 through a UART interface.

According to various embodiments, in operation 305, the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may receive an antenna connection signal from the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the second communication circuit 230 may receive an antenna connection signal from the first communication circuit 220 through the UART interface.

According to various embodiments, in operation 307, the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may connect an antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band with the first communication circuit (e.g., the first communication circuit 220) or the second communication circuit (e.g., the second communication circuit 230), based on the antenna connection signal provided from the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the second communication circuit 230 may control a plurality of switches 240 to 246 such that the first antenna 270 of FIG. 2A configured to support the first frequency band is connected to the second communication circuit 230 or the first communication circuit 220, based on the antenna connection signal provided from the first communication circuit 220.

FIG. 4 is a flowchart 400 illustrating an example operation for selecting, by a first communication circuit, a communication circuit for connecting to an antenna according to various embodiments. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, an order of each operation may be changed, and at least two operations may be performed in parallel. For example, an electronic device may be the electronic device 101 of FIG. 1 or the electronic device 201 of FIGS. 2A to 2F.

Referring to FIG. 4 , according to various embodiments, in operation 401, a first communication circuit (e.g., the wireless communication module 192 of FIG. 1 or the first communication circuit 220 of FIGS. 2A to 2F) of the electronic device may receive information related to a service priority from a second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device. According to various embodiments, when the first communication circuit 220 has received the information related to the service priority from the second communication circuit 230 through a UART interface, the first communication circuit 220 may determine that the second communication circuit 230 requests the use of an antenna configured to support a first frequency band.

According to various embodiments, in operation 403, the first communication circuit (e.g., the wireless communication module 192 or the first communication circuit 220) of the electronic device may determine whether a service is being provided through the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the first communication circuit 220 may determine whether a service using a first communication scheme (e.g., a Wi-Fi communication scheme) is being provided.

According to various embodiments, when the service is being provided through the first communication circuit (e.g., the first communication circuit 220) (e.g., “YES” in operation 403), in operation 405, the first communication circuit (e.g., the wireless communication module 192 or the first communication circuit 220) of the electronic device may identify a service priority of the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the first communication circuit 220 may identify the type of the service using the first communication scheme (e.g., the Wi-Fi communication scheme) provided by the first communication circuit 220. The first communication circuit 220 may identify a service priority corresponding to the type of the service using the first communication scheme (e.g., the Wi-Fi communication scheme) from a priority list stored in a memory (e.g., the memory 130 of FIG. 1 ).

According to various embodiments, in operation 407, the first communication circuit (e.g., the wireless communication module 192 or the first communication circuit 220) of the electronic device may identify whether a service priority of the second communication circuit (e.g., the second communication circuit 230) is relatively higher than a priority of a service being operated by the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the service priorities of the first communication circuit 220 and the second communication circuit 230 may be defined by way of non-limiting as shown in Table 1 below.

TABLE 1 priority service UWB Wi-Fi P1 Service in which Passive & Key Latency are important P2 Service in which Passive & Wi-Fi call Latency are important P3 Service that a user can AR game Mirroring, intuitively feel (e.g., a Aware display and an audio) P4 Data or sensor function Asset Tracking Data application Indoor Navigation communication

For example, in Table 1, a service priority of a key service using the second communication circuit 230 may be defined as P1, which is the highest service priority. A service priority of a call service (e.g., W-Fi call) using the first communication circuit 220 may be defined as P2. A service priority of an augmented reality (AR) game application using the second communication circuit 230 and a mirroring or aware service using the first communication circuit 220 may be defined as P3. A service priority of an asset tracking service or an indoor navigation service using the second communication circuit 230, and a data communication service using the first communication circuit 220 may be defined as P4.

According to various embodiments, when the first communication circuit (e.g., the wireless communication circuit 192 or the first communication circuit 220) of the electronic device does not provide a service related to the first communication circuit (e.g., the first communication circuit 220) (e.g., “No” in operation 403), or the service priority of the second communication circuit (e.g., the second communication circuit 230) is relatively higher than the service priority of the first communication circuit (e.g., the first communication circuit 220) (e.g., “YES” in operation 407), in operation 409, the first communication circuit may transmit an approval signal related to a connection of the antenna configured to support the first frequency band to the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, when the first communication circuit 220 does not provide the service using the first communication scheme (e.g., the Wi-Fi communication scheme), the first communication circuit 220 may determine that the second communication circuit 230 uses the first antenna 270 of FIG. 2A configured to support the first frequency band, regardless of the service priority of the second communication circuit 230. According to an embodiment, when the service priority of the second communication circuit 230 is, for example, P1 which may, for example, be the highest priority, the first communication circuit 220 may determine that the second communication circuit 230 uses the first antenna 270 regardless of the service type of the first communication circuit 220. According to an embodiment, when the first communication circuit 220 determines that the second communication circuit 230 uses the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band, the first communication circuit 220 may transmit a connection approval signal to the second communication circuit 230 through the UART interface.

According to various embodiments, when the service priority of the second communication circuit (e.g., the second communication circuit 230) is not relatively higher than the service priority of the first communication circuit (e.g., the first communication circuit 220) (e.g., “NO” in operation 407), in operation 411, the first communication circuit (e.g., the wireless communication circuit 192 or the first communication circuit 220) of the electronic device may identify whether the service priority of the second communication circuit (e.g., the second communication circuit 230) and the service priority of the first communication circuit (e.g., the first communication circuit 220) are the same.

According to various embodiments, when the service priority of the second communication circuit (e.g., the second communication circuit 230) and the service priority of the first communication circuit (e.g., the first communication circuit 220) are the same (e.g., “YES” in operation 411), in operation 413, the first communication circuit (e.g., the wireless communication circuit 192 or the first communication circuit 220) of the electronic device may transmit a shared signal related to a connection of the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band to the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, when the service priorities of the first communication circuit 220 and the second communication circuit 230 are the same, the first communication circuit 220 may determine that the first communication circuit 220 and the second communication circuit 230 share the first antenna 270 of FIG. 2A configured to support the first frequency band. In this case, the first communication circuit 220 may transmit a connection sharing signal to the second communication circuit 230 through the UART interface. For example, the sharing of an antenna may include an operation of alternately using a corresponding antenna by dividing the time during which the first communication circuit 220 and the second communication circuit 230 use the antenna. For another example, when the first communication circuit 220 and the second communication circuit 230 share a plurality of antennas, the sharing of the antennas may include an operation in which the first communication circuit 220 uses at least a part of the plurality of antennas and the second communication circuit 230 uses the remaining part of the antennas.

According to various embodiments, when the service priority of the second communication circuit (e.g., the second communication circuit 230) and the service priority of the first communication circuit (e.g., the first communication circuit 220) are not the same (e.g., “NO” in operation 411), in operation 415, the first communication circuit (e.g., the wireless communication circuit 192 or the first communication circuit 220) of the electronic device may transmit a connection rejection signal related to a connection of the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band to the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, in operation 411, when the service priority of the second communication circuit 230 and the service priority of the first communication circuit 220 are not the same, the first communication circuit 220 may determine that the service priority of the first communication circuit 220 is relatively higher than the service priority of the second communication circuit 230. For example, the first communication circuit 220 may determine that the service using the first communication scheme (e.g., the Wi-Fi communication scheme) is preferentially provided. Accordingly, the first communication circuit 220 may transmit a rejection signal corresponding to a use request of the antenna configured to support the first frequency band to the second communication circuit 230 through the UART interface.

FIG. 5 is a flowchart 500 illustrating an example operation for controlling a connection with an antenna by a second communication circuit, based on a control of a first communication circuit, according to various embodiments.

The operations of FIG. 5 described below may include, for example, detailed operations of operation 307 of FIG. 3 . In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, an order of each operation may be changed, and at least two operations may be performed in parallel. For example, an electronic device may be the electronic device 101 of FIG. 1 or the electronic device 201 of FIGS. 2A to 2F. In the following description, at least some operations of FIG. 5 may be described with reference to FIGS. 6, 7, and 8 . FIG. 6 is a diagram illustrating an example connection with an antenna in a state in which a service priority of a second communication circuit is relatively high, according to various embodiments. FIG. 7 is a diagram illustrating an example connection with an antenna in a state in which service priorities of a first communication circuit and a second communication circuit are the same, according to various embodiments. FIG. 8 is a diagram illustrating an example connection with an antenna in a state in which a service priority of a first communication circuit is relatively high, according to various embodiments.

Referring to FIG. 5 , according to various embodiments, in operation 501, a second communication circuit (e.g., the wireless communication module 192 of FIG. 1 or the second communication circuit 230 of FIGS. 2A to 2F) of the electronic device may identify whether a connection approval signal has been received from a first communication circuit (e.g., the wireless communication module 192 or the first communication circuit 220) of the electronic device. For example, the connection approval signal may include information which instructs the second communication circuit (e.g., the second communication circuit 230) to use an antenna (e.g., the first antenna 270 of FIG. 2A) configured to support a first frequency band.

According to various embodiments, when the second communication circuit (e.g., the wireless communication circuit 192 or the second communication circuit 230) of the electronic device has received a connection approval signal from the first communication circuit (e.g., the first communication circuit 220) of the electronic device (e.g., “YES” in operation 501), in operation 503, the second communication circuit may connect the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band with the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, as shown in FIG. 6 , when a service priority of P1 is provided to the first communication circuit 220 (operation 600), the second communication circuit 230 may receive a connection approval signal from the first communication circuit 220. Based on the connection approval signal, the second communication circuit 230 may determine that the second communication circuit 230 can use at least one of the first antenna 270 or the third antenna 272 of FIG. 2B, which is configured to support the first frequency band. In this case, the second communication circuit 230 may control a plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230. For example, the second communication circuit 230 may control connections of the plurality of switches 240 to 246 using a general purpose input/output (GPIO). When the second communication circuit 230 is connected to at least one of the first antenna 270 or the third antenna 272, as shown in FIG. 6 , the second communication circuit 230 may provide a service (e.g., ranging) using a second communication scheme (e.g., a UWB communication scheme) (operation 610). According to an embodiment, when the first communication circuit 220 does not operate at the time point when the second communication circuit 230 requests the use of an antenna, the second communication circuit 230 may control the plurality of switches 240 to 246 to maintain a connection between at least one of the first antenna 270 or the third antenna 272 and the second communication circuit 230 while the service using the second communication scheme (e.g., the UWB communication scheme) is maintained. According to an embodiment, when the first communication circuit 220 is in operation at the time point when the second communication circuit 230 requests the use of an antenna, as shown in FIG. 6 , the second communication circuit 230 may control the plurality of switches 240 to 246 such that the first communication circuit 220 uses at least one of the first antenna 270 or the third antenna 272 during the time when the antenna is not used by the second communication circuit 230 (operation 620). When a time point of the antenna use of the second communication circuit 230 arrives, the second communication circuit 230 may control the plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is reconnected to the second communication circuit 230.

According to various embodiments, when the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device has not received a connection approval signal from the first communication circuit (e.g., the first communication circuit 220) of the electronic device (e.g., “NO” in operation 501), in operation 505, the second communication circuit may identify whether a shared signal has been received from the first communication circuit (e.g., the first communication circuit 220). For example, the shared signal may include information which instructs the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230) to alternately use the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band, or instructs the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230) to separately use a plurality of antennas.

According to various embodiments, when the second communication circuit (e.g., the wireless communication circuit 192 or the second communication circuit 230) of the electronic device has received a shared signal from the first communication circuit (e.g., the first communication circuit 220) of the electronic device (e.g., “YES” in operation 505), in operation 507, the second communication circuit may perform control such that the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230) share the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band. According to an embodiment, as shown in FIG. 7 , when service priorities of the second communication circuit 230 and the first communication circuit 220 are equal to P2 (e.g., operation 700), the second communication circuit 230 may receive a shared signal from the first communication circuit 220. For example, the second communication circuit 230 may determine that the first communication circuit 220 and the second communication circuit 230 alternately use at least one of the first antenna 270 or the third antenna 272 of FIG. 2B configured to support the first frequency band, based on the shared signal. For example, as shown in FIG. 7 , the second communication circuit 230 may control the plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230 during a first reference time 710. As shown in FIG. 7 , the second communication circuit 230 may control the plurality of switches 240 and 242 such that at least one of the first antenna 270 or the third antenna 272 is connected to the first communication circuit 220 during a second reference time 720. For example, the second communication circuit 230 may determine that the first communication circuit 220 and the second communication circuit 230 separately use the first antenna 270 and the third antenna 272 of FIG. 2B configured to support the first frequency band, based on the shared signal. For example, the second communication circuit 230 may control the first switch 240 and the second switch 242 such that the first antenna 270 (or the third antenna 272) is connected to the second communication circuit 230. The second communication circuit 230 may control the third switch 244 such that the third antenna 272 (or the first antenna 270) is connected to the first communication circuit 220.

According to various embodiments, when the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device has received a connection rejection signal from the first communication circuit (e.g., the first communication circuit 220) of the electronic device (e.g., “No” in operation 505), in operation 509, the second communication circuit may identify whether the number of transmissions of the service priority is greater than or equal to a reference number (or the maximum number of transmissions). For example, the number of transmissions of the service priority may include the number of times the second communication circuit 230 transmitted the service priority of the second communication circuit 230 to the first communication circuit 220 for use of the antenna configured to support the first frequency band. According to an embodiment, the second communication circuit 230 may control the plurality of switches 240 to 246 to connect the first antenna 270 and the first communication circuit 220, based on the connection rejection signal. The second communication circuit 230 may identify whether the number of transmissions of the service priority is greater than or equal to the reference number (or the maximum number of transmissions) in a state in which the first antenna 270 and the first communication circuit 220 are connected to each other.

According to various embodiments, when the number of transmissions of the service priority is less than the reference number (or the maximum number of transmissions) (e.g., “No” in operation 509), in operation 513, the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may identify whether a reference time has elapsed after receiving the connection rejection signal. For example, the reference time may be defined or set randomly.

According to various embodiments, when the reference time has not elapsed (e.g., “No” in operation 513), the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may identify whether the reference time has elapsed. According to an embodiment, when the second communication circuit 230 has received the connection rejection signal from the first communication circuit 220, the second communication circuit 230 may identify whether a retransmission time point of the service priority arrives.

According to various embodiments, when the reference time has elapsed (e.g., “Yes” in operation 513), in operation 515, the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may transmit the service priority of the second communication circuit (e.g., the second communication circuit 230) to the first communication circuit (e.g., the first communication circuit 220) of the electronic device. According to an embodiment, as shown in FIG. 8 , the second communication circuit 230 may transmit the service priority (e.g., P3) of the second communication circuit 230 to the first communication circuit 220 for use of the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band (operation 800). When the second communication circuit 230 has received the connection rejection signal from the first communication circuit 220 and the reference time has elapsed, the second communication circuit 230 may retransmit the service priority of P3 to the first communication circuit 220 (operation 802 or 804).

According to various embodiments, when the number of transmissions of the service priority is greater than or equal to the reference number (or the maximum number of transmissions) (e.g., “Yes” in operation 509), the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may update the service priority of the second communication circuit to the highest value. According to an embodiment, as shown in FIG. 8 , when the second communication circuit 230 has transmitted the service priority (e.g., P3) of the second communication circuit 230 to the first communication circuit 220 as many times as the reference number (or the maximum number of transmissions), but has not received a connection approval signal (operations 800 to 804), the second communication circuit 230 may change the service priority of the second communication circuit 230 to the highest value (e.g., P1).

According to various embodiments, in operation 515, the second communication circuit (e.g., the wireless communication module 192 or the second communication circuit 230) of the electronic device may transmit the updated service priority of the second communication circuit (e.g., the second communication circuit 230) to the first communication circuit (e.g., the first communication circuit 220) of the electronic device. According to an embodiment, as shown in FIG. 8 , the second communication circuit 230 may transmit the service priority of the second communication circuit 230, which is updated to P1, to the first communication circuit 220 (operation 810).

According to various embodiments, the first communication circuit (e.g., the wireless communication circuit 192 or the first communication circuit 220) of the electronic device may change a communication circuit using the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band, based on the service priority of the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, the first communication circuit 220 may determine, as the second communication circuit 230, a communication circuit for using the antenna (e.g., the first antenna 270 of FIG. 2A) configured to support the first frequency band, based on operations 401, 403, 405, 407, 409, 411, 413, 415 (which may be referred to hereinafter as operations 401 to 415 for convenience) of FIG. 4 . When a service of the first communication circuit 220 is changed in a state where the antenna configured to support the first frequency band is being used by the second communication circuit 230, the first communication circuit 220 may compare the service priority of the second communication circuit 230 with a priority corresponding to the changed service of the first communication circuit 220. For example, when the service priority of the second communication circuit 230 is relatively high, the first communication circuit 220 may determine to maintain the use of the second communication circuit 230 for the antenna configured to support the first frequency band. In this case, the first communication circuit 220 may limit a service using the first communication circuit 220 until the driving of the second communication circuit 230 ends. For example, when the service priority of the first communication circuit 220 is relatively high, the first communication circuit 220 may determine that the first communication circuit 220 uses the antenna configured to support the first frequency band. In this case, the first communication circuit 220 may transmit a connection rejection signal to the second communication circuit 230. For example, when the second communication circuit 230 has received the connection rejection signal from the first communication circuit 220, the second communication circuit 230 may determine that the first communication circuit 220 uses the antenna configured to support the first frequency band. In this case, the second communication circuit 230 may control the plurality of switches 240 and 242 such that the first communication circuit 220 and the antenna configured to support the first frequency band are connected to each other. For example, when the second communication circuit 230 has received the connection rejection signal from the first communication circuit 220, the second communication circuit 230 may identify whether a second communication service (e.g., a UWB service) is maintained. When the second communication service (e.g., the UWB service) is maintained, the second communication circuit 230 may maintain a control of the plurality of switches 240 and 242 such that the connection between the second communication circuit 230 and the antenna configured to support the first frequency band is maintained until the second communication service (e.g., the UWB service) ends. When the second communication service (e.g., the UWB service) ends, the second communication circuit 230 may control the plurality of switches 240 and 242 such that the first communication circuit 220 and the antenna configured to support the first frequency band are connected to each other. For example, when the second communication circuit 230 has received the connection rejection signal from the first communication circuit 220, the second communication circuit 230 may control the plurality of switches 240 and 242 such that the antenna configured to support the first frequency band is connected to the first communication circuit 220.

FIG. 9 is a flowchart 900 illustrating an example operation for controlling a connection between a communication circuit and an antenna by an electronic device according to various embodiments. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, an order of each operation may be changed, and at least two operations may be performed in parallel. For example, an electronic device may be the electronic device 101 of FIG. 1 or the electronic device 201 of FIGS. 2A to 2F.

Referring to FIG. 9 , according to various embodiments, in operation 901, an electronic device (e.g., the processor 120 of FIG. 1 or the processor 210 of FIGS. 2A to 2F) may identify whether a second communication circuit (e.g., the second communication circuit 230) uses a first frequency band to provide a service. According to an embodiment, when the occurrence of an event (e.g., a key service) related to the second communication circuit 230 is detected, the processor 210 may determine whether to use the first frequency band to process the event related to the second communication circuit 230. For example, the occurrence of the event related to the second communication circuit 230 may be detected through Bluetooth or Bluetooth low power (BLE). For example, the second communication circuit may include the second communication circuit 230 of FIG. 2E, and support at least a part (e.g., 5.15 to 7.25 GHz) of the first frequency band and a second frequency band (e.g., 7.25 to 8.25 GHz).

According to various embodiments, when the second communication circuit does not use the first frequency band to provide the service (e.g., “No” in operation 901), the electronic device (e.g., the processor 120 or 210) may determine that the second communication circuit (e.g., the second communication circuit 230) uses the second frequency band (e.g., 7.25 to 8.25 GHz) to provide the service. According to an embodiment, when the second communication circuit 230 uses the second frequency band to provide the service, the processor 210 may control a second switch 242 and/or a fourth switch 246 such that at least one of the second antenna 271 or the fourth antenna 273 of FIG. 2E, configured to support the second frequency band, is connected to the second communication circuit 230.

According to various embodiments, when the second communication circuit uses the first frequency band to provide the service (e.g., “YES” in operation 901), in operation 903, the electronic device (e.g., the processor 120 or 210) may determine whether a first communication circuit (e.g., the first communication circuit 220) is in an active state. According to an embodiment, the processor 210 may determine whether the first communication circuit 220 provides a first communication service (e.g., a Wi-Fi communication service). For example, the first communication circuit may include the first communication circuit 220 of FIG. 2E and support the first frequency band (e.g., 2.4 to 2.5 GHz and 5.15 to 7.25 GHz).

According to various embodiments, when the first communication circuit is in an inactive state (e.g., “No” in operation 903), in operation 909, the electronic device (e.g., the processor 120 or 210) may connect an antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support the first frequency band with the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, when the first communication circuit 220 configured to support the first frequency band does not provide the first communication service (e.g., the Wi-Fi communication service), the processor 210 may determine that the second communication circuit 230 uses the antennas 270 and 272 of FIG. 2E configured to support the first frequency band. Accordingly, the processor 210 may control a plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230.

According to various embodiments, when the first communication circuit (e.g., the first communication circuit 220) is in an active state (e.g., “YES” in operation 903), in operation 905, the electronic device (e.g., the processor 120 or 210) may identify service priorities of the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230). For example, the service priority may be identified in a defined priority list corresponding to services provided by a communication circuit as shown in Table 1.

According to various embodiments, in operation 907, the electronic device (e.g., the processor 120 or 210) may selectively connect the first communication circuit (e.g., the first communication circuit 220) or the second communication circuit (e.g., the second communication circuit 230) with the antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support the first frequency band, based on the service priorities of the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, the processor 210 may determine that a communication circuit (e.g., the first communication circuit 220 or the second communication circuit 230) having a relatively high service priority uses antennas (e.g., the antennas 270 and 272 of FIG. 2E) configured to support the first frequency band. Accordingly, the processor 210 may control the plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the communication circuit having a relatively high service priority. According to an embodiment, when the service priorities of the first communication circuit and the second communication circuit are the same, the processor 210 may control the plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is alternately connected to the first communication circuit 220 and the second communication circuit 230.

For example, an electronic device may be the electronic device 101 of FIG. 1 or the electronic device 201 of FIGS. 2A to 2F.

Referring to FIG. 10 , according to various embodiments, in operation 1001, an electronic device (e.g., the processor 120 of FIG. 1 or the processor 210 of FIGS. 2A to 2F) may identify whether a service priority of a second communication circuit (e.g., the second communication circuit 230) is relatively higher than a service priority of a first communication circuit (e.g., the first communication circuit 220).

According to various embodiments, when the service priority of the second communication circuit (e.g., the second communication circuit 230) is relatively higher than the service priority of the first communication circuit (e.g., the first communication circuit 220) (e.g., “YES” in operation 1001), in operation 1003, the electronic device (e.g., the processor 120 or 210) may connect an antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support a first frequency band with the second communication circuit (e.g., the second communication circuit 230). According to an embodiment, when the service priority of the second communication circuit 230 is P1 and the service priority of the first communication circuit 220 is P3, the processor 210 may determine that the second communication circuit 230 uses at least one of the first antenna 270 or the third antenna 272 configured to support the first frequency band. In this case, the processor 210 may control a plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230.

According to various embodiments, when the service priority of the first communication circuit is relatively higher than or equal to the service priority of the second communication circuit (e.g., the second communication circuit 230) (e.g., “NO” in operation 1001), in operation 1005, the electronic device (e.g., the processor 120 or 210) may identify whether the service priority of the second communication circuit (e.g., the second communication circuit 230) and the service priority of the first communication circuit (e.g., the first communication circuit 220) are the same.

According to various embodiments, when the service priority of the second communication circuit (e.g., the second communication circuit 230) and the service priority of the first communication circuit (e.g., the first communication circuit 220) are the same (e.g., “YES” in operation 1005), in operation 1007, the electronic device (e.g., the processor 120 or 210) may perform control such that the first communication circuit (e.g., the first communication circuit 220) and the second communication circuit (e.g., the second communication circuit 230) share the antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support the first frequency band. According to an embodiment, when the service priorities (e.g., P3) of the first communication circuit 220 and the second communication circuit 230 are the same, the processor 210 may determine that the first communication circuit 220 and the second communication circuit 230 alternately use at least one of the first antenna 270 or the third antenna 272 configured to support the first frequency band. Accordingly, the processor 210 may control the plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230 during a first reference time. The processor 210 may control the first switch 240 and/or the third switch 244 such that the first communication circuit 220 is connected to at least one of the first antenna 270 or the third antenna 272 during a second reference time. According to an embodiment, when the service priorities (e.g., P3) of the first communication circuit 220 and the second communication circuit 230 are the same, the processor 210 may determine that the first communication circuit 220 and the second communication circuit 230 separately use the first antenna 270 and the third antenna 272 configured to support the first frequency band. Accordingly, the processor 210 may control the first switch 240 and the second switch 242 such that the first antenna 270 (or the third antenna 272) and the second communication circuit 230 are connected to each other. The processor 210 may control the third switch 244 such that the third antenna 272 (or the first antenna 270) and the first communication circuit 220 are connected to each other.

According to various embodiments, when the service priority of the first communication circuit (e.g., the first communication circuit 220) is relatively higher than the service priority of the second communication circuit (e.g., the second communication circuit 230) (e.g., “NO” in operation 1005), in operation 1009, the electronic device (e.g., the processor 120 or 210) may connect the antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support the first frequency band with the first communication circuit (e.g., the first communication circuit 220). According to an embodiment, when the service priority of the second communication circuit 230 is P3 and the service priority of the first communication circuit 220 is P2, the processor 210 may determine that the first communication circuit 220 uses at least one of the first antenna 270 or the third antenna 272 configured to support the first frequency band. In this case, the processor 210 may control the first switch 240 and/or the third switch 244 such that at least one of the first antenna 270 or the third antenna 272 is connected to the first communication circuit 220.

According to various embodiments, an electronic device (e.g., the processor 120 or 210) may change a communication circuit occupying an antenna (e.g., the first antenna 270 or the third antenna 272 of FIG. 2E) configured to support a first frequency band, based on a change in a service priority of the communication circuit.

For another example, when a service having a priority of P1 is provided through a second communication circuit 230 using channel 5 or channel 6 (e.g., the first frequency band), the processor 210 may control a plurality of switches 240 to 246 such that at least one of the first antenna 270 or the third antenna 272 is connected to the second communication circuit 230.
